LVS的配置详解配置

Red Hat Cluster Manager
　　安装操作系统，选择组件advance server，安装LVS部分。
　　两台主机，主机名为haha和hehe
　　主机haha的本地ip地址为net0:192.168.2.11，net1:192.168.2.14
　　主机hehe的本地ip地址为net0:192.168.2.12，net1:192.168.2.16
　　（主机网络连线只能用直连线进行连接，不能用交叉线连接，否则双机不能进行监控）
　　修改/etc/hosts文件，封掉localhost行的内容，写入本地主机、对方主机和虚拟主机相应的ip地址和主机名：（两台主机配置相同）
　　192.168.2.11 haha
　　192.168.2.12 hehe
　　192.168.2.13 xixi
　　进入/etc/sysconfig/rawdevices文件，增加两行内容：（两台主机设置相同）
　　/dev/raw/raw1 /dev/sdb1
　　/dev/raw/raw2 /dev/sdb2
　　以上两行是LVS需要的两个裸设备作为系统监控使用，每个裸设备的空间不能小于10M。当然需要fdisk建立两个两个相应的设备。
　　然后从起主机，进入/sbin下，./cluconfig进行cluster的配置：
　　Red Hat Cluster Manager Configuration Utility (running on haha) --haha为本地主机名
　　Enter cluster name [Red Hat Cluster Manager]:xixi --xixi为虚拟主机名
　　Enter IP address for cluster alias [NONE]:192.168.2.13 --地址为虚拟地址
　　--------------------------------
　　Information for Cluster Member 0
　　--------------------------------
　　Enter name of cluster member [haha]: --本地成员，回车即可
　　Enter number of heartbeat channels (minimum = 1) [1]: 2 --两块网卡心跳线（也可串口心跳）
　　Channel type: net or serial [net]: --第一块网卡做心跳
　　Enter hostname of the cluster member on heartbeat channel 0 [haha]: --心跳线成员名称
　　Channel type: net or serial [net]: --第二块网卡做心跳线
　　Enter hostname of the cluster member on heartbeat channel 1:hehe --另外一个成员名称
　　Information about Quorum Partitions
　　Enter Primary Quorum Partition [/dev/raw/raw1]:
　　Enter Shadow Quorum Partition [/dev/raw/raw2]:
　　Information About the Power Switch That Power Cycles Member 'haha'
　　Choose one of the following power switches:
　　o NONE
　　o RPS10
　　o BAYTECH
　　o APCSERIAL
　　o APCMASTER
　　o WTI_NPS
　　o SW_WATCHDOG
　　Power switch [NONE]:
　　--------------------------------
　　Information for Cluster Member 1
　　--------------------------------
　　Enter name of cluster member:hehe --对方成员名
　　Enter hostname of the cluster member on heartbeat channel 0: hehe
　　Enter hostname of the cluster member on heartbeat channel 1: haha
　　Information about Quorum Partitions
　　Enter Primary Quorum Partition [/dev/raw/raw1]:
　　Enter Shadow Quorum Partition [/dev/raw/raw2]:
　　Information About the Power Switch That Power Cycles Member 'hehe'
　　Choose one of the following power switches:
　　o NONE
　　o RPS10
　　o BAYTECH
　　o APCSERIAL
　　o APCMASTER
　　o WTI_NPS
　　o SW_WATCHDOG
　　Power switch [NONE]:

　　Do you wish to allow remote monitoring of the cluster? yes/no [yes]: --是否允许远程主机进行cluster监视访问
　　Configuration on this member is complete.
　　To configure the next member, invoke the following command on that system:
　　# /sbin/cluconfig --init=/dev/raw/raw1
　　Refer to the Red Hat Cluster Manager Installation and Administration Guide
　　for details.
　　本地主机配置完成
　　进入对方主机的/sbin目录，执行cluconfig ?init=/dev/raw/raw1显示信息如下：
　　Information about Channel 0
　　/sbin/cluconfig: [: haha: unary operator expected
　　Looking for host haha (may take a few seconds)...
　　Information about Channel 1
　　/sbin/cluconfig: [: hehe: unary operator expected
　　Looking for host hehe (may take a few seconds)...
　　Information about Quorum Partitions
　　Information About the Power Switch That Power Cycles Member 'haha'
　　Note: Operating a cluster without a remote power switch does not pr
　　maximum data integrity guarantees.

　　Execute "/sbin/service cluster start" to start the cluster software.
　　这时，双机软件基本配置已经完成，在两台主机上分别运行service cluster start启动服务
　　通过cluadmin进行管理，如下所示：
　　cluadmin> cluster status
